Hello David,
I called BMD phone support here in the USA. (408) 954,0500, btw.
The two jacks of the ATM Mini Pro are labeled “mic”, which leaves a lot to the imagination.
1/8″ connectors may be wired for mono or stereo, balanced or unbalanced.
According to Tony, they are unbalanced stereo line level, inputs. Probably -10, consumer line level.
AHA! Tony says the jacks can be set by software. You can set the inputs independently for -55 mic or -15 consumer line.
So I think you just have a plumbing problem.
Tony says try the following link for support at BMD: Look for Tony or Gary
